摘要： PURPOSE:To retain a preheating agent safely by a method wherein the preheating agent, arranged in the fuel of an alkaline metal, is fixed by fixing members, reacting against the alkaline metal, consisting of a metallic material burnt by an oxidizing agent and attached to the wall of the end of a combustor provided with the injection nozzle of the oxidizing agent. CONSTITUTION:A cylindrical flange 10, having an oxidizing agent injection nozzle 9, is attached to a cylindrical ring 7, fixed to one ends of water tubes 1a, 1b, and an annular supporting member 11, fixed to the inner wall of the cylindrical ring 7, is provided with a screw thread on the inner wall thereof. A preheating agent 5 is supported by fittings 2, 3, 4 and, thereafter, the cylindrical flange 10, equipped with the injection nozzle 9 of the oxidizing agent, is secured to the end of the cylindrical ring 7 through welding or the like. The lengthwise vibration of the preheating agent 5 is prevented by the fittings 2, 3 while the lateral vibration of the same is prevented by the fitting 4 whereby the preheating agent 5 may be supported rigidly in an alkaline metal 6.

摘要： PURPOSE: To provide a power unit for an underwater runner in which lithium does not reversely flow into an oxidizer supply tube after the operation is finished. CONSTITUTION: The power unit for an underwater runner comprises a closed Rankine cycle type engine which has a boiler 1 for generating steam by the heat generated from burning means which receives oxidizer via an oxidizer supply tube 9, a turbine 2 for rotatably driving a propeller by operating with the steam from the boiler 1, a condenser 4 for condensing the exhaust steam of the turbine 2, and a feed water pump 5 for supplying water from the condenser 4 to the boiler 1, wherein a filter is provided at the site near the burning means of the tube 9.

摘要： PURPOSE:To prevent decrease in discharge performance based on increase in leakage from a low to a high pressure side as well as seizure by making a side face of gear slide on a face of 'Teflon(R)' resin-made sheet of pressure recieving plate when water sucked in from an intake side and discharged from a discharge side through rotation of gear. CONSTITUTION:A shaft insertion-fitting hole 2 is provided at the central part of each gear 1 which is stored in an outer case not shown. A pressure receiving plate 3 is composed of a 'Teflon(R)' resin-made sheet 4, an adhesive agent 5, aluminium plate 6 and shim plate 7. With the constitution, when the gear 1 rotates, water taken in from an intake side is discharged from a discharge side. At this time, a side of the gear 1 slides on a face of the sheet 4. It is thus possible to attain a predetermined object.

摘要： PURPOSE:To provide a closed metallic burner through suppression of the increase of the temperature of an alkali metal by a method wherein the one end of the alkali metal is supported by the tip parts with a thin section of inner and outer cylinder bodies, an oxidizing agent injection nozzle is welded to the hole of an annular flange to mount it thereto, and the annular flange to which the oxidizing agent nozzle is welded is welded to the whole peripheral surfaces of the rear end parts of the inner and outer cylinder bodies. CONSTITUTION:A molten alkali metal 3 is inserted through an opening of the one end part, formed with water tubes 1a and 1b, in a burner body 2. A longitudinal hole is formed in a central part by means of a core, and after the alkali metal is coagulated, a preheating agent 4 is inserted in the hole. Inner and outer bodies 2-1 and 2-2, the tip parts of which has thickness lower than that of the base parts thereof are inserted in the burner body 2 in a state to make contact with the inner peripheral surface of a water tube 1a and the outer peripheral surface of a water tube 1b. The parts, having a thin section on the inner side, of the inner and outer cylinder bodies 2-1 and 2-2 are brought into contact with the one end of the alkali metal for supporting. An annular weld flange 1 to which the given number of oxidizing agent injection nozzles 7 are welded and mounted is welded to the opening part of a rear end, formed with the inner and outer cylinder bodies 2-1 and 2-2, throughout whole peripheral surfaces A and B to close the burner body 2.

摘要： PURPOSE:To prevent an injection nozzle of 6-sulfur fluoride from clogging by alkaline metal fuel, molten and scattered after igniting preheating agent, by driving a pillar type alkaline metal into the tip end of a tubular fluorine resin ring. CONSTITUTION:When 6-sulfur fluoride is injected from an injection nozzle 4 for the same, the 6-sulfur fluoride collides against the rear end of a pillar type lithium and flows through the holes 6a of a fluorine resin ring 6 while contacting with the side surface and the tip end of the pillar type lithium 10 whereby the pillar type lithium 10 and the fluorine resin ring 6 are molten and lost simultaneously within a short period of time. Thereafter the symetrical injecting combustion of alkaline metal of both sides is effected in a boiler tube. Upon preheating effected by preheating agent prior to the combustion of the alkaline metal in the boiler tube, the injection nozzle 4 of 6-sulfur fluoride is prevented from clogging by the molten and scattered alkaline metal by the pillar type alkaline metal attached to the ring 6.
